Specification of Letters Patent. I p Application filed March 4' 1907- Serial No. 360.436.

Patented Feb. 11, 1908.

To all whom it may concern. Bp it known that I, ADOLPHE ZI'iND, a citizen hf the Republic of France, residing at Paris, in France, have invented a certain.

'iiew and useful Apparatus for Massaging the Hearing Organs, of which. the following is a specification. i

This invention relates to an apparatus for the massage and physico-physiological treats merit of thehearing organ by sonorous vibrations (phono-massage) and by tactile vibration. r

One of the most practical constructions fot the apparatus according to this invention is illustrated, by way of example, in the accompanyingdrawing.

In this drawingz-Figure 1 is a vertical section of the apparatus along the longitudinal axis of its sound regulating organs. Fig. 2 is another vertical section on the line AA- of Fig. 1. I Fig. 3 is a plan of Fig. 1, the up per diaphragm-holding cover being removed Fig. 4 is an outside elevation.

This apparatus chiefly comprises an electro-magnet a which can be of the single pole,

- or of the bipolar kind, as shownin thedrawing by 'way of'c-Xample. Laterally of the soft iron core of the magnet a are arranged metal blades 0 (Z of different width and thick ness, secured, at their ends remote from the said softiron, to pillars s t, which, intheir turn, are secured to a block T!) of insulating material. u

The blades 0 (Hire provided along a portion of their length with platinum-tipped contacts e, against which rest the corresponding ends'of platinum-tipped set screws fand g mounted in an adjustable manneron lever arms Hand 11 pivoted to a cross bar y secured under the block I). These levers may be adjusted in the desired position by means of a suitable part which can b'e'operated f rom the outside :of the apparatus. In the example illustrated this part consists of a screw-threaded rod 7c, parallel to the blades 0 d, screwed into a sleeve-nut Z secured to the insulating block 6 arranged in the casing m.

The rod leis provided at its inner end with a double collar or grooved end rain which is mounted a rod 0 connecting the two levers h and-i. i

By turning the screw-threaded rod 7: by means of its outside button, the two levers h and i are simultaneously operated, in order to produce longitudinal movement of the platinum tipped set screws f and g on the platia num tipped contacts 6 of the blades 0 (1. According, to the direction'in whichv the screwthreaded rod is is turned, the length ofithe blades comprised between the. platinum tipped screws f g, and the l'ree ends of the said blades is increased or reduced, so that the number of vibrations which the said blades can give in a unit of time, is increased or reduced. Each blade can therefore produce a more or less great number of sounds or tones, according to its length. This longitudinal regulating device for the screws f 9 enables the vibrating and sonorous blade brought into action, to be compared to a violin string on which the player successively presses his fingers for varying the length of the vibrating portion.

The diaphragm or diaphragms have a double object. 1. To amplify the sonorous vibrations of the vibrating. and, sonorous blade or blades. 2. Tolact as vibro-massaging parts by transmitting to the part'to be massaged (the center of the car), while am? plifying them, the sonorous vibrations of the blades (phonic massage) and the interruptions of the current.

In the construction illustrated, the two endsof the iron cores of the electr c-magnet a are situated near a diaphragm p mounted in the. wall or cover screwed to the cylindrical frame we so that the two poles of the saidelectromagnet simultaneously acton the diaphragm. By screwlng or unscrewing the wall supporting the diaphragm p, the position of the latter can be regulatedrelatively to the poles'of the magnets", so as to enable the intensity of the sounds produced by the vibrations of the blades 0 d to be at will in creased or reduced.

When the electromagnet is a simple one,

its pole magnetizes, by means of one of its ends, the vibrating and sonorous blade or blades, and with the other end acts on the diaphragm which is then arranged in the opposite position to that which it occupies in an apparatus with double magnet. The vibrating and sonorous blades 0 (1 act in either constructionof the apparatus both as contact-breakers and as organs producing sonorous vibrations.

For the purpose of enabling only the blade which is to be operated, to'be magnetized,

the apparatus is provided with a' commu-- tater or switch which causes the current to pass either through one or the other of-the blades. In the construction illustrated,

the switch is constituted by a spindle'q connected to the circuit and operated from the outside by means of a handle 1f To the spindle q is secured a metal finger u adapted to contact with one or the other of the pillars s zcarrying the blades 0 (1, according to' the direction in which the handle ris turned. To the spindle g is also secured a cam 22 of insulating material which rests against the blade opposite to that on which the current is acti'ng,'so as to completely immobilize it. Any other device than that illustrated, acting in the same way as regards the switch and the insulation of the blades, can be used.

In operation the circuit is completed as foll0ws:-'lhe current on entering the apparatus proceeds to the switch finger n thence through either of the pillars s or t and the corresponding blade 0 or d to the contact screw f or 9 connected to the cross bar from which point the current flows around the windings of the eloctromagnet a, energizing the same, and is afterwards conducted from the apparatus.

What I claim as my invention and desire to secure by Letters Patent is V 1. Apparatus for massaging the hearing organs consisting of an electric vibrator comprising an electro-magnet and non-adjustable sonorous blades in combination with contact breaking means, contact points, an adjustable carrying device for said points by which device the length of the vibrating portion of said blades may beregulatedior the purpose specified.

2. Apparatus for massaging the hearing organs consisting of an electric vibrator comprising an electro-magnet and non-adjustable sonorous blades in combination with contact breaking means, contact points, an adwstable' carrying device for said points by which device the length of the vibrating portion of said blades may be regulated, and a diaphragm in proximity to said blades for reinforcing the sound produced thereby.

3. Apparatusfor massaging the hearing organs consisting of an electric vibrator comrising an electro-magnet, vibratory blades iaving their free ends in proximity to the poles of'said magnet, an adjustable lever in proximity to each of said blades, anadjustable contact screw in each lever, means for varying the position of the contact screws on the vibratory blades, and means for render ing one blade inoperative when desired, substantially as set forth.

4. Apparatus for massaging the hearing organs consisting of an electric vibrator comrising an electro-magnet, vibratory blades raving their free ends in proximity to the poles of said magnet, an adjustable lever in proximity to each of said blades, an adjustable contact screw in each lever, means for varying the position of the contact screws on the vibratory blades, means for rendering one blade inoperative when desired, and a microphonic diaphragm in proximity to the vibratory blades, substantially as set forth. In testimony whereof I have "signed my name to this specification in the presence of two subscribing witnesses.
